D Correct answer
Explanation

The send() method actually transmits the HTTP request to the server (with optional data payload). Option A describes open() which initializes the request. Option B describes getResponseHeader() which retrieves header values. Option C describes abort() which cancels the request. Since none of A-B-C correctly describe send(), D is the correct choice.
